Flora of North America species comparison

leaves generally larger than branch leaves, 1.3– 1.8 × 0.8–1 mm;

elliptic to lingulate-spatulate, widest above middle, hyaline cells nonseptate.

pink, superficial cortical cells aporose.;

stem leaves narrowly triangular to lingulate- triangular, 1.2–1.6 × 0.6–0.8 mm, length: width ratio ca. 2:1, apex apiculate, border strong and moderately broadened basally;

hyaline cells narrowly rhomboid and 1 to occasionally 2 septate, often fibrillose apically.

long-cylindrical, branch leaves terete to sometimes distinctly squarrose in shade forms.

not 5-ranked.

1–1.4 mm, ovate to ovate-lanceolate, gradually narrowed to an involute tip, hyaline cells somewhat bulging on concave surface and nearly plane on convex surface, with 4–8 large, elliptic, unringed pores per cell on convex surface and 1–4 irregularly rounded pores per cell on concave surface, internal commissural walls smooth to rather strongly papillose, chlorophyllous cells ovate-triangular with the widest part at or close to the convex surface.

1.3–1.5 × 0.5–0.55 mm, ovate-lanceolate, concave, straight, apex involute;

hyaline cells on convex surface with numerous round to elliptic pores along the commissures, grading from large elliptical pores at the base to moderate-sized round pores at the apex, concave surface with a few large round pores scattered throughout.

dioicous.

unknown.

proximal and distal surfaces smooth, papillae indistinct;

proximal laesura 0.5–0.6 spore radius.

fascicles typically with 3 spreading (sometimes 2) and 2 pendent branches.;

branch stems with single layer of cortical cells.
